Windows 7 and GBPVR

[mila06]

I have build a new rig and installed windows 7 and gbpvr. Most of things are fine but every now and then livetv hiks every 2-3 sec. I see this on both MPEG 2 and MPEG 4(h264). If livetv starts without the hiks, they never come.... If the hiks are there when i starts livetv, i restarts gbpvr and everything is normaly fine. It's not the hardware. All recordings are always fine!

Do you tweak win 7 to get gbpvr deliver it's best ?? (i have seen something about deleting some dll to get win 7 to not controling the codec).

This should put you on the right track:
http://thegreenbutton.com/forums/t/78749.aspx - Step 7 under 'configuring the tools' is all you need, apart from installing ffdshow or whatever.
Basically you need to 'take ownership' of the DMO codecs, and just rename them to stop them working - then you can use whatever codec you want. I think it only applies to MP3 and MPEG2 - I only disabled MP3DMOD.DLL as it was the only way I could get Ffdshow to be used in Windows 7 (so I could use the dolby prologic decoding for DivX/XviD files with MP3 sound).
It could be that you need to try other codecs for Mpeg2 and Mpeg4, as I have not seen anything like the 'hiks' you describe in Windows 7 (except when any OSD menus are present in EVR)

I didn't need to do any of that. Those steps should only be required for Media Foundation applications and not for GBPVR which is DirectShow.

mila06, zip and post your pvrx2*.log files (including the native) when this happens. It will tell you for sure which decoders are being used.

[mila06]

Just got it again. I have attached the logs.

EDIT: I have tried other audio decoders than MS

[whurlston]

It looks like you have the Microsoft decoder set as your prefered AC3 and MPEG audio decoders:

Code:

2009-11-25 22:19:51.727    VERBOSE    getSetting(PreferredAC3AudioDecoder)
2009-11-25 22:19:51.735    VERBOSE    AC3 audio decoder filter: Microsoft DTV-DVD Audio Decoder

2009-11-25 22:19:51.757    VERBOSE    MPEG1Layer2 audio decoder filter: Microsoft DTV-DVD Audio Decoder

But AC3Filter is getting loaded in there as well:

Code:

In the "System" tab of the AC3Filter configuration, make sure you have "PCM" unchecked and you should also have "Prefer other decoder" selected.

Thanks whurlston....

I have changed the ac3-settings, but why is gbpvr/windows loading the AC3 filter?. It's not in my gbpvr-config

[whurlston]

If you had PCM or "Prefer AC3Filter" checked in the AC3Filter config, it will automatically insert itself into practically every graph including the ones created by GBPVR for playback/live tv. This is why I had you change it in the AC3Filter Config and not the GBPVR config.

Did the changes solve your problem? If not, post another set of logs after viewing LiveTV or a recording.

I DON'T GET HIKS ANYMORE!!!! It's most amazing. Thank you so much, whurlston.

Both were checked in system-tab in AC3filter Config.

[whurlston]

Great. I double checked your new logs and the graph now seems to be created properly.

I thought the same, but I just could not get ffdshow to play MP3's in 64-bit Win7. I installed DsfMgr and ffdhshow audio decoder was the highest priority decoder - apart form the list at the end - codecs with 'unknown' against merit, which includes the MS DMO codecs. Taking ownership of the MS MP3 decoder and renaming it was the only way I could get ffdshow to be used.
Maybe it's because I used media player first, and accepted it's standard settings to be the default player of MP3's?
